One of the good things (err, maybe the only thing...) about the new HbA1c measurement scale introduced recently is that the relevant numbers are completely different to those you see on your meter. I think one of the difficulties with the "old" scale is that because it was so similar to mmol/l, people often made the mistake of misinterpreting the numbers. It was easy to think that a result of 7% was reasonably good, when actually this translates to an average mmol/l figure of nearly 9, which is way off good.
And as for the actual number on whatever HbA1c scale is used, the lower the better as far as I'm concerned?
